Researchers at the University of Tennessee are exploring possible medical applications for plant-based nanoparticles. Researcher Mingjun Zhang said his team is particularly interested in the potential of the organic nanoparticles to improve nuclear imaging. Zhang said plant particles can degrade more slowly in the body, allowing for more accurate imaging, and they also could be used as tools to deliver drugs.

Sen. John Kerry, D-Mass., today is set to host meetings between FDA Commissioner Dr. Margaret Hamburg and the state's medical device and biotech companies. In the first roundtable meeting, members of the Massachusetts Medical Device Industry Council will discuss with Hamburg proposed changes to the 510(k) clearance process, among other issues. Meanwhile, executives from the Massachusetts Biotechnology Council and Hamburg will focus their discussion on various issues, including follow-on biologics and personalized medicine.

The passage of the American Medical Isotope Production Act of 2011 will allow for the creation of the right model of the medical nuclear supply chain that will ensure adequate supply of the radioisotope technetium-99m, which is sourced from molybdenum-99, wrote professors Anna Nagurney and Ladimer Nagurney from the University of Massachusetts, Amherst, and the University of Hartford, respectively, in this opinion piece. The creation of such a model will allow "the ability to analyze the medical nuclear supply chain vulnerabilities, and synergies, as well as to explore the relevant costs and risks," the experts wrote.

Tennessee Valley Authority's proposed modular reactor in Oak Ridge, Tenn., should be supported, according to a newspaper editorial board. The modular reactor would be less expensive than a nuclear plant, while providing another source of clean energy, the editorial board wrote. "Oak Ridge represents a new generation of nuclear power plant design -- simpler, safer, standardized. If successful, it can be a model for the future of American nuclear energy," the board added.
